MIXING FAUCET.

Application filed December S, 1924-. Serial No. N455?.

My invention relates to faucets and especially to faucets for mixing anddeliver'- ing two fluids, such as syrup and water, and one of theobjects of my invention is the provision of a faucet 'of simple.construction which thoroughly mixes the fluids as they pass through it.

The invention possesses otherl objects and features of advantage, someof which, with the foregoing, will `loc set forth in the follow ingdescription of the preferred forni ofnry invention which is illustratedin the drawings accompanying, and forming part of the siiecilication. .tis to be understood that I do not limit myself to the showing made bythe said drawings and description. as l may adopt variations of thepreferred forni within the scope of my invention as sel' forth in theclaims.

Referring to the drawings;

Figure l is a side elevation of my faucet, showing the same mounted.upon a panel.

Figure :2 is a vertical sectional View of the faucet mechanism.

Figure 3 is a plan view of the face of the valve seat, the direction inwhich it is taken, being indicated by the arrow 3 of Figure 2.

-Figure 4l is a plan view of t-he face of the valve, the direction ofthe view being indicated by the arrow 4; of Figure 2.

The faucet of my invention comprises a head 2 having a threaded nipple3, to adapt the head for connection to a water pipe 4, which preferablyextends thru the panel 6 and is surrounded by the usual Yflange 7. iwater passage 8 extends thru the nipple and terminates in a port 9 onthe horizontal valve seat ll, formed on the under side of the head andsurrounded by the flange l2.

The head is also formed with a second and larger syrup passage 13, whichalso opens on the valve seat 1l in the port 14, and on the top of thehead, is in communication with the socket or cup 1G, adapted to supportand receive the regulated quantities of syrup from the receptacle 17 inthe well known manner. There is thus provided thru the head, anunobstructed passage 8 for water and an unobstructed passage 13 for thesyrup from the container 17.

Rotatably mounted on the valve seat is the valve 21, having a stem Q2extending upwardly thru the head and secured at the top by the nut 23. Awasher 24 having apertures therein alined with the ports 9 and lll, ispreferably interposed between the valve and its scat, and the pressureof the valve on the seat regulated hy the nut 23 seating against thewaslur 26 mounted on the squared end of the valve stein Since the washerturns with the valve stein, movement of the latter does not tend toloosen the nut Q3. A handle 27 provides .iueans for turning' the. valve7and movement of the valve is `limited by enoagtnnent of the handle `withthe ends 2&3 ot a recess formed in the flange l2, which permits amovement of the, valve thru an are of about 90 degrees.

The valve face in contact with the valve seat is also provided withports 3l and 32. so placed that with the handle 2T in the on positionthey are in register with the ports 9 and lll respectively, and suchports 9 and let are covered when the handle .is in the olf position.Ports 3l and are the ends of passages 323 and Bel. respectively, whichextend thru the valve and open on the under side thereof. Ilfhe nozzle36 concentric with the valve, and adapted to discharge syrup from thepassage axially of the valve, is threaded into the bottom of the valve,and an annular splash cup 37, is disposed on the. nozzle 3G in suchposition as to receive the water discharging from the passage 33.

Surrounding the inner nozzle 3G is an outer nozzle 38 threaded on thevalve 2l. and having a discharge orifice in line with the inner nozzle.The lower portion of the outer nozzle. about the discharge aperture 39,is contracted; and the upper portion of the outer nozzle is relativelylarge so that a mixing chamber il is provided within the outer nozzle.

lt will be observed that the syrup flowing thru the passage 1S cornesfrom the cup 16 and is under the lightest of pressures, since there isbut an inch or two of head. The water flowing thru the passage S,however, is under the normal pressure existing in a water distributingsystem and for this reason the passage 8 is considerably smaller thanthe passage 1?). These passages are of course properly proportioned inaccordance with the conditions.

lllhen the valve is turned to aline the ports 3l and E). and 3Q and. ll.syrup from 'he container 17 flows by `gravity thru the passage 'i3 intothe passage 34 and out of the inner nozzle 36. At the same time waterunder the normal distributing system pressure is jetted into the splashcup 37, which diffuses the jet into a spray, throwing it violentlyagainst the inner surface ol the outer nozzle 38. It then runsdownwardly and thoroughlyY mixes with the stream of syrup issuing fromthe nozzle 3G, the mixture being delivered from the outer nozzle thruthe aperture 39 into the dispensing glass.
